STARTING AND STOPPINGMECHANISM.

To all whom "it may concern.-

Be it known that 1, JOHN H. MIOHENER, J12, a citizen of the UnitedStates, and a resident of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements inStarting and Stopping Mechanism, of which the following is aspecification.

This invention relates to starting and stopping mechanism.

In its illustrated embodiment it is particularly adapted for use inconnection with trimming mechanism.

It is in the nature of improvements on the invention set forth in myallowed application for Letters Patent of the United States filed Aug.31, 1908, Serial Number 451,064 for improvements in trimming mechanism.

. Theobject of thepresent invent-ion is to 7 provide means, first, forautomatically starting one section of the distributing mechanism from acontiguous section already in operation, when that portion of the bunkerin which. said operating section is located is filled with coal up tothe point of location of the starting trip lever; second, forautomatically stopping the automatically started section when thatportion of the bunker in which it is located is filled with coal uptothe point of location of the stop tripping lever. With these ends inview my improved mechanism comprises devices and combinationsillustrated in the accompanying drawings wherein V Figure 1 is a planview of a portion of two runs of endless chain with operating and stopand starting mechanism therefor.

Fig. 2 is a side elevation corresponding with Fig. 1 Fig. 3 is a planview of a modification of one feature of my improvements. Figs. 4, 6,and 8 are front elevations of a portion of my improvements illustratingsuccessive steps in the operation. Figs. 5, 7

and 9 are side elevations corresponding with Figs. 4, 6 and 8respectively.

Referring now more in detail to Figs. 1 and 2, one or more verticalshafts as 4 are supported for rotation in bearings as 6, fixed in deck 2and projecting upwardly and downwardly therefrom. Said shafts have fixedto their lower ends sprocket wheels 3, 5 on which are supported endlesschains 7, 8 all respectively. Said chains are provided Specification ofLetters Patent.

- with the usual blades as 9 on chain 8. The upper ends of the sprocketshafts, as 4, have bevel gears 10, 11 fixed thereto respectively.

On horizontal shaft 17 suitably supported from deck 2 and above shaft 4in bearings as 14, is fixed bevel gear 13 meshing with bevel gear 11.Turning freely on said shaft 17 and meshing with bevel gear 10 is bevelgear 12. Said gear 12 has pin 15 projecting therefrom for engagementwith slot 16 in clutch member 18 slidably mounted on shaft 17. Saidclutch member 18 is caused to rotate with shaft 17 by means of key 19 incoengagement with said clutch member and shaft.

Gears 12, 13 are shown so located relative to gears 10,11 thatcontiguous runs of chains 7, 8 will travel in the same direction, asindicated by their respective arrows. End- ,wise movement of shaft 17 isprevented by collars 20, 21 pinned thereto and in engage- .ment withopposite faces of bearing 14. Power may be communicated to-shaft 17 byany suitable means not shown.

Located contiguous to and parallel with shaft 17 is slidable rod 22 inbearings 23 and 24 upstanding from deck 2. Clutch operating arm 25 ispinned to said shaft and has its forked end 26 in engagement with groove27 in clutch member 18. Thus endwise movement of rod 22 toward boX'23will throw slot 16 of clutch member 18 into engagement with pin 15 ofgear 12 causing said gear to be driven by shaft 17 and, subsequentlyendwise movement of rod 22 in the other direction will throw the clutchout of engagement and leave gear 12 at rest.

The means which I have provided for moving rod 22 endwise .for throwingthe clutch in and out of engagement are as follows: For limiting theendwise movement of said rod 22 collar 28 is pinned thereto forengagement with boX 23 and collar 29 is pinned thereto for engagementwith box 24. At the outer end of rod 22 collar 30 is pinned thereto. Onthe outboard end of said rod between collar 30 and box 24 are twosliding collars 31, 32 with compression spring 33 therbetween. Pivotedat 34 in bracket 35 on deck 2 is lever 36 the upper arm of which isprovided for engagement with collar 30 to hold rod 22 in its rearwardposition (Figs. 4, 5) with the clutch out of engagement. The'lower armof said lever 36 is connected by link 37 to tripping mechanism to behereinafter described. At 38 in bracket 39 on deck 2 is pivoted anotherlever 40 similar to lever 36. The upper end of said lever 40 is providedfor en gagement with sliding collar 32 and the lower end thereof isconnected by link 41 to tripping mechanism to be hereinafter described.Lever 42 is pivotally mounted on post 43 outstanding from bracket 44 ofbearing 24. Post 43 is parallel to rod 22 and lever 42 is slidable onsaid post. Rod

22 has notch 45 therein for engagement with' lever 42. The function ofsaid lever is to furnish temporary abutment, through collar 31. for oneend of spring 33.

For operating lever 42 the following means are provided: Lever 40 isfixed to one end of pivot shaft 38 and on the other end thereof is fixedbent lever 46 having its upper arm 460 extending horizontally forengagement with lower end of lever 42.

Referring now more particularly to Figs. 1 and 2 link 37 has itsrearward end pivot ally connected to one arm of lever 47 pivoted at 48under deck 2. The other arm of said lever reaches over one run of chain8 and into the path of trip pin 49 of said chain when said pin is in itsupper or operative position. Said pin 49 is slidably mounted in saidchain and is urged to its lower or inoperative position by spring 50between fixed collar 51 on said pin and chain 8. Pivotally mounted at 52on said chain and slightly in advance of pin 49 is bell crank arm 53.The horizontal arm thereof is in operative engagement with pin 49between fixed collars 51, 54 thereon. The vertical arm of bell crankterminates in blade 55 for engagement with the coal. Chain 7 is providedwith pin and bell crank arm 57 in all respects similar to pin 49 and armof chain 8 just described. Also link 41 is attached to lever 59 pivotedat 60 all similar respectively to lever 47 and so forth of link 37.

The operation of my improved mechanism is as follows: The mechanismbeing in a state of rest with the parts in the relative positionsillustrated in Figs. 1. 2. 4 and 5 shaft 17 is started revolving in thedirection of its arrow; thereupon gear 13 thereon, in mesh with gear 11on shaft 4 of sprocket 5 will drive chain 8 in the direction of arrow80. Blade 9 on said chain will thereupoi'l scrape coal in its path.horizontally as shown at 90 Fig. 2. When said blade has carried saidcoal horizontally beyond a point below lever 47 blade 55 of bell cranklever 53 will drag through the accumulated coal and said lever will pushupwardly pin 49 into the path of lever 47 and the upper end of said pinwill engage the projecting end of said lever 47 and push it to thedotted position of Fig. 1. Link 37 thereupon swings lever as into theposition of Figs. 6 and 7. The withdrawal of lever 36 from engagementwith collar 30 of rod 22 allows spring 33, abutting against collar 32and lever 40, to move rod 22, through collar 31 and lever 42, slidablymounted on post 43 and locked into notch 45 in said rod 22, endwise tothe left, Fig. 6. This throws clutch member 18 into engagement with pin15 of gear 12 thereby starting said gear in rotation. Said gear, in itsturn, through gear 10 on the shaft of sprocket 3 starts said sprocket inrotation and chain 7 thereon moving in the direction of arrow 70.

Referring now to Fig. 3, I have therein illustrated means for postponingthe tripping of lever 470 by pin 49 for two or more circuits of said pinon chain 8. I change lever 47 from one of the first class to one of thesecond class as shown at 470 Fig. 3 and interpose between the free endof said lever and pin 49 a star wheel (301 pivoted at 61 and having anydesired number of arms, in the present case four are shown. Said starwheel has a projection 62 on one of its arms, for engagement with lever470. The parts illustrated in Fig. 3 are shown at the moment of trippingwith pin 49 against arm 600 of star wheel 601 and projection (32 againstthe free end of lever 470.

Returning to the description of the operation of the means for stoppingchain 7, blade 71 now scrapes forward the coal 72 in its path until theforward end of said pile has passed a point below lever 59. Thereuponblade 58 of lever 57 drags through said pile pushing upwardly pin 56into position for engagement with lever 59 all similar in operation tothat described in connection with chain 8 and lever 47. Lever 59 isthereupon swung on its pivot (30 and link 41 pulls lever 40 from behindcollar on rod 22 allowing said collar to be forced, by spring 33, towardthe right hand (Fig. 8,) against colla" 30. At the same time lever 46,fixed to shaft 38 of lever 40, by its upper arm 460 forces lever 42 outof engagement with notch 45 thereby permitting spring to force lever 42through collar 31 against bearing 24. it fixed abutment for the lefthand end (Fig. 8) of spring 33 is thereby furnished. and rod 22 is freefor movement toward the right hand by means of said spring actingbetween said abutment and sliding collar 32 against fixed collar 30 onrod .There upon said movement of rod 22 to the right takes place (Fig.8) and clutch member 18 is withdrawn from engagement with pin 15 of gear12. Said gear thereupon comes to rest and chain 7 is stopped. Thestarting and stopping mechanism is now ready to be reset to the positionof Figs. 1, 2, 4 and 5 and the operation repeated.
